This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Regulatory framework 

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following:

• legislative requirements, including work health and safety (WHS)
• industry codes of practice and guidelines
• environmental regulations and guidelines
• Australian and other standards
• licence and certification requirements

All operations to which this unit applies are subject to stringent health, safety and environment (HSE) requirements, which may be imposed through state/territory or federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence.

Procedures 

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, include one or more of the following:

• emergency procedures
• work instructions
• standard operating procedures (SOPs)
• safe work method statements (SWMS)
• formulas/recipes
• batch sheets
• temporary instructions
• any similar instructions provided for the smooth running of the plant

Hazards 

Hazards include one or more of the following:

• gases and liquids under pressure
• structural hazards
• equipment failures
• industrial (machinery, equipment and product)
• equipment or product mass
• plant services (steam, condensate and cooling water)
• limited head spaces or overhangs
• working at heights, in restricted or confined spaces, or in environments subjected to heat, dusts or vapours
• flammability and explosivity
• hazardous products and materials
• unauthorised personnel
• sharp edges, protrusions or obstructions
• slippery surfaces, spills or leaks
• extreme weather
• other hazards that might arise

Work requirements 

Work requirements may include one or more of the following:

• fitting, tubing and thread specifications
• fitting brand
• specific sealing method and type
• process line and process materials
• parts and equipment required
• local detectors requiring isolation
• required skill level
• conflicting work

Work requirements come from briefings, handovers, and work orders and include one or more of the following:

• compliance documentation
• product specifications
• nature and scope of tasks
• achievement targets
• operational conditions
• lighting conditions
• plant or equipment defects
• hazards and potential hazards
• coordination requirements or issues

Job site 

Inspecting job site includes identifying one or more of the following:

• location
• authorisations required
• access and egress needs
• hazards
• recent work undertaken on joint
• fitting type (matches specification)

Implementing hazard controls 

Implementing hazard controls includes one or more of the following:

• selection and use of appropriate personal protective equipment (PPE)
• obtaining appropriate authorisations
• checking required isolations
• controlling other work in area
• controlling access to area
• using gas tester
• verifying and confirming isolation
• safe fitting breaking procedure (line of fire)

Inspecting components 

Inspecting tube fitting components includes one or more of the following:

• full tube insertion
• orientation of ferrules
• correct tube deburring
• for signs of damage, defects or deterioration in all components
• confirming compliance of components

Components 

Components includes, but are not limited to, one or more of the following:

• fitting body
• fitting nut
• front ferrule
• rear ferrule
• tube
• tube clamps and support saddles

Refer 

Refer means to refer the issue to the person with the required skills, knowledge and/or authority to deal with the matter.

Checklists and records 

Checklists and records include one or more of the following:

• paper or electronic based
• verbal/radio reports
• reporting items found which require action

Action 

Action in response to problems includes the following:

• determining problems needing action
• accessing and applying relevant technical and plant data
• applying appropriate problem solving techniques to determine possible fault causes
• rectifying problem using appropriate solution within area of responsibility
• following through items initiated until final resolution has occurred
• reporting problems outside area of responsibility/ability to resolve to designated person

Action includes one or more of the following:

• replacing existing components with new components
• carrying out minor maintenance within operator's skill level
• identifying and reporting problems outside operator's competence
• identifying and controlling hazards related to tube fitting joints

Routine problems 

Routine problems must be resolved by applying known solutions.

Routine problems are predictable and include one or more of the following:
